How to fetch children of node via webroot path in Gentics Mesh?

Question

I have a webroot path of a parent node and would like to return the children of this node. Using https://demo.getmesh.io/api/v1/demo/webroot/images/ for example just yields the node itself.

Answer 1

There is currently no way to load the children of a node via REST using a single request. You can however load the node of the path. Use the uuid of that node and load the children via /api/v1/:projectName/nodes/:nodeUuid/children

A much more elegant approach however would be to use the following graphql query. I highly recommend this option since it is more efficient when handling large datasets.

Background: Computing the totalCount / totalPage size is costly and you can avoid this by using hasPreviousPage and hasNextPage.

You can use the following graphql query:

query ($path: String) {
  node(path: $path) {
    children(perPage: 5) {
      hasNextPage
      hasPreviousPage
      currentPage
      elements {
        uuid
        fields {
          ... on vehicleImage {
            name
          }
        }
      }
    }
  }
}

Query variables:

{
  "path": "/images"
}
